Abstract

Open Archives Initiative Object Reuse and Exchange (OAI-ORE) defines standards for the description and exchange of aggregations of Web resources. OAI-ORE introduces the notion of a Resource Map, an RDF Graph [RDF Concepts] which describes the Aggregation, the Aggregated Resources of which it is composed, and the relationships between them (and/or the relationships between these and other resources). Since a Resource Map is an RDF Graph, it can be serialized using any RDF syntax. This document outlines the use of RDFa [RDFa Syntax] to serialize Resource Maps. A companion document [ORE RDFXML] outlines the serialization of Resource Maps using RDF/XML [RDFXML Syntax].

This document is intended for implementers who have an understanding of ORE concepts and are responsible for the development of applications which generate or process Resource Maps using RDFa. Readers who want a high-level understanding of the motivation for ORE, and of the solution it provides, should read the ORE Primer [Primer]; readers who want further details of the RDFa syntax should consult the W3C RDFa specification [RDFa Syntax].

This is one of several documents comprising the OAI-ORE specifications and user guides.

1. Introduction

Open Archives Initiative Object Reuse and Exchange (OAI-ORE) defines standards for the description and exchange of aggregations of Web resources. OAI-ORE introduces the notion of a Resource Map, an RDF Graph [RDF Concepts] which describes the Aggregation, the aggregated Resources of which it is composed, and the relationships between them (and/or the relationships between these and other resources. Since a Resource Map is an RDF Graph, it can be serialized using any RDF syntax. This document outlines the use RDFa [RDFa Syntax] to serialize Resource Maps.

The RDFa in XHTML specification [RDFa Syntax] describes how to encode an RDF Graph within an HTML or XHTML document using a set of attributes. RDFa makes use of existing HTML/XHTML markup and content so that the same data which is typically rendered to a human reader is used as the basis of the content of the RDF Graph and the need to repeat content is minimised.

1.1 Notational Conventions

The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [IETF RFC 2119].

This specification uses the common term URI to mean both IRI [RFC3987] and URI [RFC3986].

1.2 Namespaces

This specification uses the following namespaces and prefixes to indicate those namespaces:

Prefix Namespace URI Description
dc http://purl.org/dc/elements/1.1/ Dublin Core elements
dcterms http://purl.org/dc/terms/ Dublin Core terms
foaf http://xmlns.com/foaf/0.1/ FOAF vocabulary terms
ore http://www.openarchives.org/ore/terms/ ORE vocabulary terms
xsd http://www.w3.org/2001/XMLSchema# XML Schema Datatypes
rdf http://www.w3.org/1999/02/22-rdf-syntax-ns# RDF vocabulary terms
rdfs http://www.w3.org/2000/01/rdf-schema# RDFS vocabulary terms
eptype http://purl.org/eprint/type/ Eprints type vocabulary
repo info:eu-repo/semantics/ Driver object type vocabulary

1.3 Conformance

Where an XHTML document containing RDFa is used to serialize an ORE Resource Map, that XHTML+RDFa document MUST be a strictly conforming XHTML+RDFa document as described in the RDFa in XHTML specification [RDFa Syntax].

A consumer of ORE Resource Maps encoded in RDFa MUST support all of the syntactic conventions defined by RDFa.

2. Summary of Recommended RDFa Syntax

The RDFa syntax provides some flexibility in the way an RDF Graph is encoded. The aim of this section is not to provide a full description of the RDFa syntax, but rather to provide some recommendations on how the RDFa syntax can be used to encode an ORE Resource Map. It is not a requirement that this particular set of conventions is used. To encode an ORE Resource Map, a provider of ORE Resource Maps MAY use any of the syntactic conventions defined by RDFa.

Simplifying considerably, in RDFa:

The following example is an XHTML+RDFa document (adapted from [RDFa Primer]) constructed according to the rules above.

        <h2 property="dc:title">The trouble with Bob</h2>

        The trouble with Bob is that he takes much better photos than I do:

        <div about="http://example.com/bob/photos/sunset.jpg">
          <img src="http://example.com/bob/photos/sunset.jpg" />
          <span property="dc:title">Beautiful Sunset</span>
          by <span rel="dcterms:creator">
               <span property="foaf:name">Bob</span>
           </span>.
        </div>
     </div>
    </div>
  </body>
</html>

XHTML+RDFa, RDF/XML via RDFa Distiller, NTriples via RDFa Distiller

The XHTML+RDFa document encodes the following RDF triples (assuming the URI of the document is http://example.org/blog/):

Subject Predicate Object
<http://example.org/blog/> cc:license <http://creativecommons.org/licenses/by/3.0/>
<http://example.org/posts/trouble_with_bob> dc:title "The trouble with Bob"
<http://example.com/bob/photos/sunset.jpg> dc:title "Beautiful Sunset"
<http://example.com/bob/photos/sunset.jpg> dcterms:creator <_:bnode1>
<_:bnode1> foaf:name "Bob"

The subject URI of the first triple is the URI of the document; for the three subsequent triples, the subject is determined from the value of the about attribute. The predicates are determined from the values of the rel attribute (in the first and third cases) and the property attribute in the other. The objects are determined from the value of the href attribute (in the first case) and the content of the element with the property attribute in the subsequent cases.

The last two triples illustrate the use of a "blank node" (or "bnode"). Blank nodes MAY occur in ORE Resource Maps when asserting the creator of or contributors to the Resource Map, the Aggregation, or Aggregated Resources. In the example shown, the creator of the photograph is "Bob", but Bob has no associated URI. Instead the special "_" (underscore) prefix (and an arbitrary local part with no global meaning, in this case bnode1) is used to identify the blank node in the fourth and fifth lines in the table of triples.

Note that this is not intended to be a full description of the RDFa processing rules; for that information, see RDFa in XHTML: Syntax and Processing [RDFa Syntax].

2.1 URIs in RDFa

In RDFa, an RDF URI reference is always encoded as the value of an XML attribute.

The attribute values may take the form of a URI in full or of a relative reference, to be resolved relative to a base URI, either a URI provided by the use of the XHTML base element, or the URI of the document itself.

Some of the attributes used in RDFa also support the encoding of a URI in an abbreviated form as a CURIE or "compact URI". The use of a CURIE allows the author to replace the leading section of a URI with a substitution token which is mapped to a URI. The full URI represented by a CURIE is obtained by concatenating the second part of the CURIE onto the URI to which the substitution token is mapped. The mapping of substitution token to URI is expressed using an XML Namespace declaration. This mechanism is quite similar to that used in RDF/XML to map URIs to XML QNames, with the important difference that the lexical constraints on CURIEs are less stringent than those on QNames, so that any URI can be abbreviated as a CURIE, whereas, as noted above, there are some URIs which can not be mapped to QNames.

The attributes used by RDFa vary in their support for these different ways of representing URIs:

The following three examples (extracted from the RDFa in XHTML Syntax and Processing document [RDFa Syntax]), illustrate three different ways of encoding the URI http://dbpedia.org/resource/Albert_Einstein as the value of the about attribute, in the first case as a URI represented in full, and in the latter two cases as a CURIE

  <div>
    <div about="http://dbpedia.org/resource/Albert_Einstein">

    </div>
  </div>

 

  <div xmlns:db="http://dbpedia.org/">
    <div about="[db:resource/Albert_Einstein]">

    </div>
  </div>

 

  <div xmlns:dbr="http://dbpedia.org/resource/">
    <div about="[dbr:Albert_Einstein]">

    </div>
  </div>

For a full description of the mechanism for mapping CURIEs to URIs, see the section "CURIE and URI Processing" in RDFa in XHTML: Syntax and Processing [RDFa Syntax].

2.2 Choice of URIs in the Splash Page Scenario

One application for RDFa is to encode a Resource Map within a human readable XHTML page describing an Aggregation. In repositories of scholarly documents and other applications, such pages are often referred to as Splash Pages. It is also possible that the Splash Page be included as one of the Aggregated Resources of the Aggregation.

Within the ORE Model, the URI of the Resource Map (URI-R) MUST be distinct from the URI of the Aggregation (URI-A). Similarly the URI of a Splash Page (URI-S) MUST be distinct from the URI of the Aggregation (URI-A).

It is RECOMMENDED that the URI of a Splash Page be distinct from the URI of the Resource Map if the Splash Page is itself an Aggregated Resource.

For further discussion of URI choice with RDFa serialization, see implementation with RDFa or microformats in [ORE HTTP].

3. Example of Resource Maps Encoded in RDFa

The remainder of this section uses the an e-print in arXiv with a "splash page" at http://arxiv.org/abs/astro-ph/0601007 to illustrate a possible XHTML-RDFa encoding of a Resource Map. This is an interesting example because it has multiple identifiers, versions, formats, mirrors and external relationships. For illustrative purposes, the example diverges from the real e-print in arXiv in the manner that it associates an aggregation of data with the e-print.

These examples use the following URIs for the Aggregation (URI-A) and Resource Map (URI-R). As specified, the URI-A of an Aggregation should be distinct from the URI of a splash page.

The ordering of the following subsections correspond to that used to introduce features in the Abstract Data Model Specification [Abstract Data Model]. Each section header links to the corresponding Abstract Data Model section. The examples are not intended to be exhaustive, but sufficient to demonstrate the RDFa syntax.

3.1 Relationship between a Resource Map and an Aggregation

A Resource Map MUST include one triple with an ore:describes predicate. The subject of this triple MUST be the URI-R of the Resource Map. The object is the URI-A of the Aggregation described by the Resource Map.

The triples corresponding to the example are:

Subject Predicate Object
Assertions about Resource Map
http://arxiv.org/rem/xhtml/astro-ph/0601007 ore:describes http://arxiv.org/aggregation/astro-ph/0601007

Note: The use of bold in the XHTML+RDFa example above indicates the segment of the XML that corresponds to the triples in the table that immediately preceeds the example. This visual cue will be used throughout this document.

3.2 Metadata about the Resource Map and Aggregation

A Resource Map MUST include triples expressing minimal metadata properties about the Resource Map. It MAY include triples expressing additional metadata properties about the Resource Map. Finally it MAY include triples expressing metadata properties about the Aggregation.

3.4 Relationships between the Aggregation and Similar Resources

A Resource Map MAY include one or more triples, with URI-A as the subject, which assert that the Aggregation is a Resource with content that is similar to another Resource. The predicate MAY be either rdfs:seeAlso or its sub-property ore:similarTo.

The triples corresponding to the example are:

          <span property="dcterms:abstract">
            We construct the non-canonical kinetic term of a k-essence field directly
            from the effective equation of state function $w_k(z)$, which describes the properties
            of the dark energy. Adopting the usual parametrizations of equation of state we
            numerically reproduce the shape of the non-canonical kinetic term and discuss some
            features of the constructed form of k-essence.
